Wet overflow ball mill - Yantai Jinpeng Mining

The main component of wet overflow ball mill is a cylinder with bigger diameter and smaller length which is revolved by transmitting machinery. Materials are put in cylinder through the feed opening and then thoroughly grinded. The falling course of iron balls and ores can produce huge falling impact and autogenous grinding. The continuous feeding ...

Ball Mill - an overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.
